CAR VENTILATOR Application led September 8, 1930. Serial'No. 480,565. 4

This invention-relates to ventilators and more particularly to aventilator for use in connection with a railway car,'although it is tobe `understood that it may be applied to any structure for which it maybe found suitable. The present invention constitutes an improvement uponthe construction shown in Patent,No.`1,746,009, obtained vby 4me andJosephI A. Bombard February 4, 1930.

Oneobject of the invention is to provide a car ventilator adapted to vbeapplied to a window frame or other portion of a carin operative relationto an opening formed therein whereby fresh air may pass into the car andair within the car suckedl outwardly'when the car is in motion.

Another object of the invention is to provide an improved closure foraneck extending through an opening in the window frame 2o or car walland so mount this closure that it may be easily moved to aclosed or to apartially or fully opened positionand thereby control passage of airinto and out ofthe car.

Another object `of the invention is to so mount the closure that itsmovements through the neck maybe guided and the e X- tent of movementlimited, thereby permitting the closure to be very easily moved toV aclosed or an opened position and atv the same time prevent the closurefrom being drawn out of the neck too far when opened. Y l

Another object of the invention is to provide improved Vmeans forguiding passage of air through the ventilator when the closure isopenand very effectively prevent inwardly and outwardly moving air frominterfering with each other and becoming intermingled.

Another object of the invention is to lprovide the closure with wallsthrough which air may pass having screeningso applied thereto that therewill be no danger of the screening catching against walls of the neckinto which the closure fits and becoming detached or loosened when theclosure is moved to adjusted positions.

Another object of the invention is to provide a device of this characterwhich will be very neat in appearance and of such construction that itwill operate properly with a car moving either forwardly or rearwardly.

panying drawings, wherein Figure l is a perspectivel view looking at theinterior of a car having the improved ventilators applied to its windowframes,`

Fig. 2 is a view in elevation looking at the ventilator from outside thecar, portions of vthe ventilator beingl broken away,

Fig. 3 is a longitudinal sectional view takenv on the line 3-3 of Fig.2,and i Fig. 4 is a transverse sectional viewV taken on the line 4*-4 ofFig. 3.

The ventilator is adapted for use in connection with a railwaycar,fsu`ch as shown in Fig-- ure l and indicated in general by thenumeral l, and in this figure the ventilators 2 have The invention isillustrated inthe accom? 55 spaced relation to its ends and at it-s endsare disposed other screens 6 which together with the screensl 5 serve toprevent cinders fromV blowing into the open endof the body facing thedirection in which the car is moving. It should be noted that the openends of the body aredisposed in planes converging` downward-fv lys'othat rain can not easily drive into the vent'ilatorsand that since thebottom of thev r body slopes downwardly toward its open ends'any rainwhich may enter the` body will 7 of the body is formed intermediate itslength with anopening and about, this o ning is disposed a neck 8whichis engage through an 'opening 9 formed in thejwindow frame or wall'of the car. This'neckfits snugly in the opening and when screws` l() arepassed through theJ ears 11 extendingfrorn the ends of the inner walland engaged in the window frame the ventilatorwill be very securelyheldinv place. The collar-8 and the opening en- ,drain outof the same. Theinner side wall i closed thereby are elongated longitudinally of theventilator and the length is such that the collar may be divided intoend sections of such dimensions that air can very easily pass throughthe neck into and out of the car.

In order to close the open end of the neck and control passage of airthrough this neck, there hasbeensprovided a closure l2. This closurelhasa head lfformed of sheetzm-etal and walls 14. The head is of greaterdimensions t-han the neck and of the sameoutline and Ythe -wallsarevcfthe same outline asv the neck and of such dimensions that the closurehas snug telescoping fit within the neck, as clearly shown in Figures 3and Il. Therefore,

the closure may be slidl through the neckinto.

and out of a. closed position and when closed marginal portions of thehead will bear against a facing band 151secured against :the inner taceofftliewindow frame inl-overlappingxrelat-iontotheopeni-ng 9V and wallsof the neck. Theclosure-wall is of an open constructionl-in .'orderztopermit `free passage of air-.whemthe closure is open and 'hascircumferentially extendingfstrips or bands lr6 connected by `spacedbars or vstrips '17. 'Screening 18 is secured against thein-ner surfacesof the Walls and servesrvery effectively to screen air passing throughthe closure as well as constitutinga. reinforcement for the walls.Therefore,.t heclosure may be :grasped by its handle.19fandthrustintothe neck or drawn outwardly l.therefrom without dangerof bendingftl-ie strips la. A partitionor plate 20 is secured in theclosure intermediate its length, and from an inspection of Figures 3 and#Lit will be seen that this plate ext/ends transversely inthe-closure.with one endifixed to the head 13 and its side edges secured tothe'walls of the closure. A companion partition 2l is mounted in thebody andthis partition consists of plates or sheets 22 Ywhich aresecuredfvto'the outer side wall of the body andare curved, as showninfFigure 3, so that theylextendfro-m.the outer side wall in convergingrelationto each other. Reducedportions 23 ofthe partition plates:22,eXtend-in-to the neck iin Vparallel relation to each otherandthesereduced endportions which are of less-length then the `Vdepth`of the neck have theirlfreeends bent t0 form lips '24 extending ingdiverging relationto each other. .By this arrangementtheflips will serveto guide the partition-plate ,2 0y between the .reduced'ex tensions2370i' the partition plates 22 when the closure isfittedinto the neckand since the plates from which the partition 2l is formed are resilienttheywill have close contactingengagement with` opposite side faces oftherpartiti'on plate'20 and therebyicause the .tubular bodypvof 'theventilator and its neck tofbe divi'dedinto air passages leading from.oppositev ends ofthe body .and at Vtheir inner ends extendingithroughthe neck. e Since thevbody portion vandgneck ofthe ventilatorhavefbeendivirded intoseparate air passages, air imay-pass-inwardlythrough-one air pasguide and limit movement of the closure and in orderto do vso there has beenyprovided posts 25 carried f -by the lventilator-body 'and projecting into the neck near opposite ends lthereof andstems 26 secured aga-inst the inner face of the closure head nearopposite ends thereof. Tlieposts are hollow and slidably receive thestems and each stem carries alpin 27 'which projectstra-nsversel'ywtherefromandisengagedthrough aslot 28fformedlongitudinally in its cooperatingpost'. yTherefore-sliding movement ofjthe closurelwill be gnidedby-the stems .which areslidably yrevceivedlintheihollow-posts and-thelfact that the stems' carry pinsengaged through slots in the posts will ylimit l sliding movement fofthe stems and Athereby prevent the closure from being draw-noutward'lyfbeyond yalposition in `whiehit-is engaged in thevneck. .ItWill thusbeseen .that there will be no danger ofthe: closurelbeing drawnoutvtoo far byan inexperienced:- person opening the ventilator.
